  • The peculiar object P/2010 A2, discovered in January 2010, is in an asteroidal orbit in the inner main asteroid belt and was given a cometary designation because of the presence of a trail of material. These authors report observations of P/2010 A2 by the Rosetta spacecraft. They conclude that the trail arose from a single event, an asteroid collision that occurred around 10 February 2009.

  • When the Philae lander bounced on the surface of comet 67P/Churyumov–Gerasimenko, it exposed primitive icy-dust material within cometary boulders; the intrinsic strength and porosity of this material is reported.

  • The ‘onion-like’ stratification of the two lobes of the comet 67P/Churyumov–Gerasimenko reveals that its unusual shape is the result of a gentle collision merging two kilometre-sized objects in the early stages of the Solar System.

  • The size and spatial distribution of pits on comet 67P/Churyumov–Gerasimenko, which are active and probably created by a sinkhole process, imply that large heterogeneities exist in the physical, structural or compositional properties of the first few hundred metres below the current cometary surface.
